Simple question...If you have a vaccum secondary Holley, Edelbrock, Carter...etc. All of the same CFM, and all tuned right, how can one make more power than the other?

 

It can't. But that little qualification about each being "tuned right" is the real issue.


------------------
94 Firebird Formula M6- No options but Z rated tires. No mods over $10. 13.5@105.
79 Malibu "beater" w/junkyard 400 SBC, tweaked QJet 4bbl, finally a decent set of heads, a few other tricks. A maddening 13.000001 @ 108 on the motor with little traction. No nitrous runs with the new heads yet.
Grandma's old 78 Malibu (33K miles!) soon to have the powertrain from the 79 put in it.

"One of the last remaining QJet tuners on Planet Earth!"

 

What Damon said....some carbs are more tunable, and more easily tunable than others. Also, some work better on lower vacuum engines than others.

Hell..why be vauge..both the above reasons are why Holleys and thier knockoffs are the king
